20 Things You Somehow Missed In There Will Be Blood
12. Plainview Wasn't Actually Mining
There are times even the best need the help of special effects to make things believable. David Fincher uses them for their convenience, even when he can shoot on set or on location. So there's nothing wrong when certain mishaps like this one in There Will be Blood happen. There are almost zero uses of special effects in the film.
If someone did mention that the effects were indeed used, one would imagine it for other scenes, like the oil derrick burning, or the levers falling down in the drilling hole. But actually, it is used in one of the first scenes of the film. When Daniel is still an unsuccessful hustler, circa 1898, he mines and looks for silver and gold.
We can clearly spot the made-up CGI sparks in that scene. Before Plainview picks into them, some places give way to misplaced special effects being used. It is a small detail but proves that Day-Lewis does not do everything in character.
